MMPU2--6-10 cm of water; 1-2 cm of sediment.
Has had ruoff thorugh and past it with complete
filling evident.

MMPU5--
Sand package heading toward it about 2 m upstream.
It looks like a small dam formed by vegetation just
downstream from the trap caused more still water
and accumulation of fines and leaf and wood debris.
Could have had 10-20 cm of water above the top
of the trap (indicated by jetsam).

MMPU4-->10 cm thick, channel wide coarse sand
has moved into the trap. It has had 10-30 cm
scour around its back. FLow has been > 10 cm
above top of trap. Excavated debris below has
been removed in channel.

MMPU1--Entry is still very flush. Flow and scour
down stream removed excavated debris. 20-30 cm
water and 4->10 cm sediment, including some
conical coarse sand accumulations on upstream
